  フォト蔵 API 使って画像をアップロードするやつ

  Usage:

    $userid = "フォト蔵に登録したメールアドレス";
    $password = "パスワード";
    $Photozou = new \Photozou( $userid, $password );
    // パラメータ詳細は http://photozou.jp/basic/api_method_photo_add を参照
    $params = array(
      "photo"       => "/path/to/test.jpg",
      "album_id"    => "アップロード先のアルバムID",
      "photo_title" => "test.jpg アップロードテスト",
      "date_type"   => "date",
      "year"        => 2014,
      "month"       => 9,
      "day"         => 12,
    );
    $result = $Photozou->photoAdd( $params );
    print_r( json_decode( $result ) );

  Todo:

    画像形式チェックとかファイル名チェックとか
    HTTPレスポンスヘッダ確認とか
